STEAM-TRAP.

SPECIFICATION forming part of Letters Patent No. 583,394, dated May 25,1897.

Application filed July 6, 1896. Serial No. 598,116. (N0 model.)

To @ZZ whom t may concern:

Be it known that I, GEORGE SEGUR BRAIN- ERD, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Steam-` Traps,of which the following is a specification.This invention relates to a steam-trap of the general construction shownin Letters Patent of the United States No. 546,606, granted to meSeptember 17, 1895; and it has for its object to provide certainimprovements on the construction set forth in said patent whereby thedisconnection and assemblage of the parts of the trap are rendered moreconvenient.

The invent-ion consists in the improvements which I will now proceed todescribe and claim.

The accompanying drawing, forming a part of this specification,represents a side elevation, partly in section, showing a. trapembodying my improvements.

In the drawing, a represents a chamber for the reception of steam andwater of condensation. In the upper portion of said chamber is an inleth, with which is connected a supplypipe c, through which the steam andwater of condensation enterthechamber. On one end of the chamber isformed a iiange ci', having a faced and planed outer surface to form atight joint with the removable end piece or head CZ. The flange a isprovided below the chamber a with an outlet-pipe, which is preferablycomposed of a pipe-section 2, formed integral with the flange andprojecting from the side thereof opposite that upon which the removableend piece d bears, and another section 3, which is detachably secured bymeans of bolts 4 4 to the section 2.

e represents a valve-Casin g which is secured to the end piece CZ and islocated within the chamber ce and contains a valve f, with which isconnected a Hoat-lever g, pivoted at g to an ear h, aflixed to the endpiece d. The valve-casing communicates with the upper end of theoutlet-passage i, formed in the end piece d, the lower end of saidpassage communicating with the section 2 of the outletpipe. Thevalve-casing and the valve are constructed so.that when the valve isdepressed it shuts off communication between the interior of the chamberand the outlet-passage fi. Vhen the valve is raised by an accumulationof water in the chamber, said water acting on the float-lever andraising it to the position shown in dotted lines, communication isopened between the interior of the chamber and the outlet-passage c'.

j represents a by-pass which is connected with the supply-pipe c abovethe chamber a and with thesection 3 of the outlet-pipe below thechamber. Said by-pass is provided with a valve j', whereby it may beclosed. The supply-pipe is provided with a valve c', constructed toprevent the passage of steam and Water into the chamber a and at thesame time permit their passage into the by-pass, so that the use of thetrap maybe discontinued without interrupting the i'low of the steam andwater, the valve c being adjusted to prevent the entrance of steam andwater into the chamber d and the valvey" opened to permit the steam andwater to ow to the waste-pipe through the by-pass j.

It will be observed that the movable end piece d, which supports thevalve-casing and the float-lever, is entirely independent of theoutlet-pipe and may be removed with said float-lever and valve-casingfrom the chamber a without disturbing either the outletpipe or theby-pass. This independent removability of the end piece d, with theioatlever and the valve-casing, distinguishes my present constructionfrom that shown in my former patent above mentioned, in which theby-pass and outlet are shown as connected directly with the removableend piece which supports the float-lever and valve-casing, said formerconstruction necessitating the disconnection of the by-pass and outletfrom the removableend piece before the latter can be removed to permitaccess to the float-lever and valve-casing. It will be seen that theimproved construction enables the trap to be much more convenientlytaken apar-t and assembled than heretofore.

7s represents a pipe connecting the lower portion of the chamber d withthe by-pass j, said pipe having a valve lo. The bottom of the chamber ais inclined, as shown, from the removable end piece CZ to the pipe 7c,so that sediment accumulating in the chamber can be readily removed byopening the valve la', the inclination of the bottom of the chamberpermitting the sediment to flow through the pipe 7c into the by-pass.The section 3 of IOO the outlet-pipe is connected with the by-pass by tsection 5, having a. valve G. The valves 6 and 7a arel closed when theuse of the trap is discontinued.

I claim- The improved steam trap, comprising' t chamber having an inletin its upper portion and a flan ge at one end provided with anoutlet-pipe below the chamber, said pipe extending from the rear side ofthe flange, t valve-casing within the chamber, L valve in said casing, apivoted float-lever connected with the valve, a supply-pipe connectedwith the inlet of the chamber, the by-pass connecting the supply-pipewith the outletpipe, a valve whereb7 the bypass may be opened andclosed, n valve in the supply-pipe between the by-pass and chamberwhereby the supplypipe may be closed to discontinue the operzi- A whenthe trap is not in operation, and the end piece or head removablysecured to the outer side of said iiange, and supporting the floatleverand valve-casing said end piece being provided with an outlet-passagewhich connects the valve-casing with the outlet-pipe when the end pieceis in place, the outletpipe and by-pnss being entirely independent ofthe end piece so that the end piece, with the oat-lever andvulve-casing, may be removed from the chamber without disturbing theoutlet and by-pztss.

In testimony whereof I have signed my name to this specification, in thepresence of two subseribin g Witnesses, this 2d day of July, A. D. 1896.

GEORGE SEGUR BRAINERD.
